I spent two hours trying to figure out why, whatever the configuration settings I threw at it, a laptop would not connect to a wireless connection. Turns out the culprit was Norton Internet Security. Only by running the Norton Removal Tool was I able to fix the computer.

Ooooh, how fun, they say. 169.254.x.x is the IANA-defined black-hole. Oops. Of course, rebuilding the IP stack or turning off IPv6 didn’t help. Sigh. Probably recommending that everyone remove Norton now now that MS Security Essentials, AVG, Ad-aware, etc etc do a better job without destroying the computer while updating.
